Minimizing Rational Functions by Exact Jacobian SDP Relaxation Applicable to Finite Singularities [PDF]
, 2012 This paper considers the optimization problem of minimizing a rational function. We reformulate this problem as polynomial optimization by the technique of homogenization. These two problems are shown to be equivalent under some generic conditions.

Optimal error estimate for a system of several quasi variational inequalities
Journal of Inequalities and ApplicationsThis paper presents and examines a finite element approximation for a system of multiple quasi-variational inequalities. We analyze these inequalities, including terms for sources and obstacles that depend on the solution itself.

Hierarchy Strengthened Grey Wolf Optimizer for Numerical Optimization and Feature Selection
IEEE Access, 2019 Grey wolf optimizer (GWO) is an efficient swarm intelligence algorithm for kinds of optimization problems. However, GWO tends to be trapped in local optimum when solving large-scale problems.
